Temporary storage of hazardous waste is a key focus area in environmental protection inspections. Many enterprises only attach importance to end-of-pipe disposal but take temporary storage lightly. Problems such as leakage, mixed storage and missing ledgers, once identified, will result in rectification requirements at best and penalties at worst. According to industry reports, the annual output of industrial hazardous waste in China reaches approximately 420 million tons. Environmental cases caused by non-compliant storage account for 31.7% of all hazardous waste-related cases. This figure reminds enterprises that selecting the right temporary storage cabinet is only the first step. Without sound daily management, compliance inspections will still be hard to pass.1. Risks in the Temporary Storage Link Are More Concentrated Than ImaginedWaste-generating enterprises tend to prioritize waste transit over temporary storage. Daily waste comes in diverse categories with widely different chemical properties. Random piling in the same area can easily trigger chemical reactions. Self-built hazardous waste rooms often suffer from many problems: damaged anti-seepage layers, insufficient ventilation and incomplete ledgers. Poorly planned temporary storage zones with overstacked materials, and emergency supplies placed too far away for rapid response in case of leakage, are also common issues. Small and medium-sized factories often lack forward planning and rush to make renovations only when environmental inspections are approaching. These problems are not isolated cases; they are becoming a major source of penalties.2. Hardware Compliance Is the Bottom Line; Storage Cabinets Must Meet StandardsTraditional hazardous waste rooms involve long approval cycles and high investment. Hazardous waste temporary storage cabinets, which are movable and customizable, are more suitable for small and medium-sized waste-generating enterprises. Three core indicators must be considered when selecting cabinets:- Seepage prevention: The cabinet bottom shall be equipped with an integrally molded leak-proof tray with a volume of no less than 110% of the capacity of the largest single container.- Ventilation: Forced ventilation shall be provided at a rate of no less than 6 air changes per hour, and the combustible gas alarm shall be interlocked with the exhaust system.- Material: The cabinet shall adopt double-layer cold-rolled steel plates filled with fireproof rock wool, with a fire resistance rating of no less than 1 hour.3. Installing Cabinets Without Proper Management Is a Waste of EffortCommon on-site problems lie not in hardware, but in process and detail control. Missing zone identification, insufficient employee awareness, vague requirements for incompatible waste isolation, and perfunctory daily inspections are widespread issues. Management should focus on three key points:- Classified and zoned storage: In principle, each cabinet shall hold only one category of hazardous waste; acids and alkalis shall not be mixed, and oxidizers shall be isolated from reducing agents.- Closed-loop ledger management: Full-process records of warehousing, storage and outbound delivery shall be kept for no less than five years.- Personnel training: Employees shall be clear about which wastes cannot be stored together, where emergency supplies are located, and the first steps to take in the event of leakage.Only when hardware and management advance in tandem can risks be reduced.4. Intelligent Temporary Storage Cabinets Replace Manual Control with Systemic ManagementManual ledgers are prone to omissions and loss, and on-site inspections cannot achieve round-the-clock coverage. Intelligent hazardous waste temporary storage cabinets are changing the situation. They support swipe-card access for waste deposition, automatic weighing, real-time data upload and automatic generation of digital ledgers. When the hazardous waste inventory in the cabinet reaches the upper limit, the platform automatically pushes a collection and transportation work order. Temperature, humidity, VOCs and combustible gases are monitored by sensors. Abnormal conditions trigger automatic alarms, which are interlocked with the exhaust system. The system supports remote access, allowing managers to check the status via mobile phones. This mechanism turns the slogan of traceable sources, trackable destinations and accountable responsibilities into a data-driven chain.5. Installation Alone Is Not Enough; Daily Operation and Maintenance Determine Long-Term ComplianceHazardous waste storage management is a long-term task, not a one-time project. Cabinets shall be inspected weekly for corrosion, welds and door seals. Leak-proof trays shall be checked daily for accumulated liquid, and collection drums must not overflow. Ventilation openings and sensors shall be cleaned and calibrated regularly, and alarm functions shall be operational at all times.Enterprises cannot stop at construction and delivery; subsequent operation and maintenance also require continuous implementation. They shall customize temporary storage cabinet solutions based on their own waste types and generation volume, and support them with corresponding inspection management specifications. By putting daily control in place in advance, enterprises can reduce environmental risks, respond smoothly to environmental supervision, and avoid unnecessary economic losses.6. Common Deduction Points in InspectionsThere are many common deduction points during inspections: unlocked cabinets accessible to unauthorized personnel; incomplete label information with only "waste liquid" marked — labels shall include name, category, code and hazard characteristics; unclear compatibility grouping with acids and alkalis stored in the same cabinet; accumulated liquid in leak-proof trays not cleaned in time; blocked ventilation openings and malfunctioning alarms; discrepancies between ledgers and actual inventory with missing dates or quantities; expired emergency supplies and insufficient absorbent cotton. These details may seem minor, but they directly affect inspection results.7. Emergency Material Configuration Determines Response Speed After LeakageAbsorbent cotton, oil-absorbent felts and sandbags shall be placed beside temporary storage cabinets, along with chemical protective gloves, goggles and fire extinguishers. Leakage emergency drums shall be placed close to the cabinets and kept unlocked. Signs shall be clear and employees shall be trained to use the equipment. Leakage drills shall be conducted quarterly, with records of drill time, participants and corrective actions. Emergency response capability is not a formality; it is the last line of defense.8. Proactive Planning Ensures Calm Response to InspectionsMany enterprises mistakenly believe that purchasing cabinets guarantees compliance, but compliance is an ongoing process. Identification, ledgers, training and inspections are all indispensable. Temporary storage cabinets are not all-purpose solutions; they require institutional support and personnel execution.The earlier enterprises sort out their waste generation lists, define zoning plans and establish inspection mechanisms, the better. The more detailed daily management is, the calmer inspections will be. The lower the environmental risks, the more stable production will be.Temporary storage of hazardous waste is not a one-time project. Choosing the right cabinet is the first step, but sound daily management is the key. With proactive planning and continuous control, enterprises can face environmental inspections calmly, pass inspections smoothly, and reduce losses from on-site rectification and production shutdowns.

Recently, two sets of intelligent battery storage cabinets from DeSUN ECOTECH have been successfully delivered from the domestic factory to the customer’s site in Germany, completing a one-stop delivery process covering scheme design, manufacturing, export certification, international logistics and on-site deployment. This is not merely a product export, but also a concentrated demonstration of DeSUN ECOTECH’s technical capabilities, compliance competence and engineering service capabilities in the field of battery safety storage. Facing the strict safety and environmental access requirements of the German and EU markets, the product has successfully entered European industrial application scenarios by virtue of its professional multi-layer protection design, intelligent monitoring system and complete international certifications. Focusing on Full-Scenario Battery Storage to Reshape Safety Management Standards With the rapid development of new energy vehicles, energy storage systems and the consumer electronics industry, the demand for temporary storage of batteries in different states — finished, waste and pending testing — continues to rise. Safety risks in the battery storage link are characterized by high concealment, rapid chain reactions and severe secondary hazards. Once thermal runaway, short circuits, electrolyte leakage or harmful gas release occur, they can easily trigger fires, explosions and environmental pollution accidents. DeSUN ECOTECH’s intelligent battery storage cabinets are specially developed for temporary storage scenarios throughout the entire battery life cycle. Designed in accordance with relevant standards such as the Management Specification for Recycling of Traction Batteries for Vehicles – Part 2: Recycling Service Outlets (GB/T 38698.2-2023), the products focus on fire protection, explosion protection, short circuit prevention, thermal runaway prevention and all-round monitoring, and are applicable to multiple links including battery production, recycling, testing, operation and maintenance turnover. The company’s "intelligent and digital retired battery storage equipment" was selected into the 2025 Catalogue of Practical Technologies and Typical Projects for Ecological Environmental Protection, gaining national-level recognition and fully reflecting its professional accumulation in the fields of environmental protection and safety. Seven-Layer Safety Protection to Build an Active Defense System From structural design to functional configuration, these battery storage cabinets are developed around the actual risks of battery storage, forming a multi-layer safety protection system. In terms of fire and explosion protection, the cabinet body adopts high-strength explosion-proof steel with a three-layer fireproof structure, endowing the entire cabinet with explosion-proof capability. The cabinet is equipped with pressure relief explosion-proof valves or pressure relief devices. When the internal pressure rises sharply due to battery thermal runaway, they can release pressure directionally, effectively reducing the risks of cabinet rupture and secondary combustion and explosion. In terms of short circuit prevention, an insulating isolation layer is installed inside the cabinet to physically avoid abnormal contact between battery positive and negative electrodes and reduce fire hazards caused by short circuits. Meanwhile, the cabinet supports zoned isolated storage, where batteries of different specifications, states of charge and safety levels can be stored separately. This not only facilitates refined management, but also avoids cross risks caused by mixed storage. For temperature-sensitive batteries, the cabinet is equipped with an intelligent constant temperature control system that can be accurately adjusted within the range of -10℃ to 60℃. It adapts to the differentiated storage temperature requirements of different types of batteries, and reduces the risks of accelerated battery aging due to excessive temperature or performance degradation due to low temperature. In terms of leakage prevention and environmental treatment, an anti-leakage tray is designed at the bottom of the cabinet. In the event of battery electrolyte leakage, it can effectively contain the liquid and prevent corrosive liquid from overflowing and contaminating the ground and environment. To address the problem that harmful gases such as fluorides are easily generated from the leakage of battery anode materials, the product is specially equipped with waste gas purification facilities, which adopt chemical materials for neutralization and filtration treatment to ensure that waste gas meets emission standards, balancing storage safety and environmental protection. In addition, the product supports the configuration of auxiliary function modules such as charging and discharging, which can meet the practical needs of battery charging and maintenance for batteries pending testing, further improving the applicability of the product in testing and operation scenarios. Intelligent Digital Management for Visible and Controllable Risks Different from traditional storage cabinets, DeSUN ECOTECH’s intelligent battery storage cabinets emphasize "active monitoring, intelligent early warning and data traceability". The product is equipped with an all-round monitoring system that can collect key parameters such as internal temperature, smoke and combustible gas in real time. When abnormal monitoring data occurs, the system can send early warning signals in time to gain disposal time for on-site personnel, and can link safety measures such as ventilation and power off according to preset logic to reduce the risk of accident escalation. The digital management platform can record storage environment data, alarm information and operation status, helping enterprises achieve refined management and safety traceability in the battery storage link. This mode of "hardware protection + software monitoring" upgrades temporary battery storage from passive protection to active risk management, which is more in line with the requirements of modern enterprises for work safety and digital operation. Complete Certifications for Smooth Entry into the German Market As a product exported to Germany, compliance is a key link that cannot be ignored. DeSUN ECOTECH’s intelligent battery storage cabinets have obtained relevant export certificates such as CE certification and ATEX international explosion-proof certification, meeting the requirements of EU directives and standards in terms of mechanical safety, electromagnetic compatibility and explosion protection. The German market has extremely high safety and environmental thresholds for industrial equipment. The smooth certification and delivery of the product to the customer’s site fully demonstrates that its design, manufacturing and performance have reached the international advanced level. The two sets of cabinets exported this time were fully delivered by DeSUN ECOTECH in a one-stop manner, from factory production to on-site deployment at the German customer’s site. The company completed relevant certifications and tests in advance, adopted a packaging protection scheme suitable for sea transportation and long-distance transit, and followed up the whole process of international logistics, customs clearance and on-site delivery, ensuring that the products can be quickly installed and put into use after arriving in Germany. This one-stop delivery capability reduces customers’ burdens in cross-border procurement, compliance review and engineering coordination, and also lays a solid foundation for subsequent expansion of the European market.

As the core carrier for the storage and supply of industrial gases, gas cylinders are widely used in laboratories, chemical engineering, manufacturing, healthcare and other scenarios. Improper storage of cylinders containing oxygen, acetylene, nitrogen, argon and other gases may cause leakage, combustion, explosion or tipping accidents. Current national standards such as the Safety Regulations for Handling, Loading/Unloading, Storage and Use of Gas Cylinders (GB/T 34525-2017) put forward systematic requirements for the design of gas cylinder rooms.Combining two typical scenarios of indoor and outdoor application, DeSUN ECOTECH has launched large and small intelligent gas cylinder storage cabinets, providing an integrated hardware solution for the implementation of standardized management.I. Design Specifications for Indoor Gas Cylinder Rooms: Representative of Laboratory ScenariosIndoor storage mainly caters to gas consumption scenarios such as laboratories, medical institutions and small processing sites. The specifications require that: cylinder rooms shall be set independently or adopt dedicated gas cylinder cabinets, kept away from heat sources, open flames and flammable substances; good ventilation shall be maintained to prevent the accumulation of flammable gases; gas cylinders must be equipped with anti-tipping measures to avoid valve damage and leakage caused by tipping; flammable gases and combustion-supporting gases shall be stored in separate zones; leakage alarm devices shall be installed, and dedicated personnel management and ledger records shall be implemented.Meanwhile, indoor gas cylinder cabinets shall have fireproof and explosion-proof performance, and the cabinet materials shall be flame-retardant and corrosion-resistant to meet the fire isolation requirements for a certain period of time in emergency situations. For space-constrained places such as laboratories, the equipment shall also feature compact size and convenient operation.In response to these requirements, DeSUN ECOTECH’s small intelligent gas cylinder storage cabinets adopt flame-retardant steel and a three-layer fireproof structure, with full-cabinet explosion-proof performance to effectively resist external fire sources. The cabinet is equipped with adjustable fixing brackets, compatible with gas cylinders of various specifications from 2L to 40L, to prevent tipping. An intelligent leakage monitoring system detects cylinder leakage in real time and triggers alarms in case of abnormalities.With a compact size, it can be placed in laboratory corners, outpatient gas points or storage areas of auto repair shops. It is fitted with a simple lock to realize dedicated personnel management, avoid accidental contact and loss, and is suitable for temporary storage and daily use of a small number of cylinders.II. Design Specifications for Outdoor Gas Cylinder Rooms: Large-Batch Centralized StorageOutdoor gas cylinder storage is commonly found in production areas of chemical enterprises, gas consumption zones of manufacturing plants, large-scale laboratories and gas supply stations, featuring a large number of stored cylinders, diverse gas types and variable environmental conditions. The specifications put forward higher requirements for outdoor cylinder rooms: they shall be kept away from fire sources and densely populated areas, and have rain-proof, sun-proof, lightning-proof and anti-static functions; natural or forced ventilation shall be maintained to discharge leaked gases in time; flammable, combustion-supporting and inert gases shall be stored in separate zones and separate warehouses; clear safety warning signs shall be set up; gas concentration monitoring, pressure and temperature parameter collection and early warning systems shall be equipped; gas cylinders shall be fixed to prevent tipping; batch storage sites shall also be equipped with explosion-proof electrical equipment and digital management capabilities to realize full-process traceability of gas cylinders.DeSUN ECOTECH’s large intelligent gas cylinder storage cabinets are designed for such large-scale scenarios, in strict compliance with standards including GB/T 34525-2017. They integrate an intelligent monitoring system that collects real-time data of cylinder pressure, temperature and liquid level, triggers automatic audible and visual alarms in case of abnormalities and uploads data to the management platform. The ventilation system can discharge leaked gases in time to prevent combustion and explosion caused by the accumulation of flammable gases. Fixed anti-tipping brackets are compatible with cylinders of different specifications to eliminate tipping and leakage.The cabinet body adopts thickened explosion-proof steel with anti-corrosion surface treatment, resistant to high and low temperatures and impact, adapting to harsh outdoor environments. The full-cabinet explosion-proof design meets the requirements of explosion-proof ratings such as Ex IIB T4/T6 and Ex IIC T4/T6, and has been certified by authoritative institutions. Meanwhile, the intelligent management system supports traceability of cylinder warehousing, outbound delivery and service life, realizing full-process digital management and meeting the comprehensive needs of outdoor cylinder rooms for batch storage, safety monitoring and accountability traceability.III. Synergy of Indoor and Outdoor Scenarios: One-Stop Standardized ImplementationFrom a regulatory perspective, indoor cylinder rooms focus on space adaptation, fire and explosion protection, and dedicated personnel management; outdoor cylinder rooms emphasize large-batch storage, environmental tolerance, centralized monitoring and explosion-proof ratings. The two products from DeSUN ECOTECH complement each other: the small intelligent gas cylinder storage cabinets address daily safe storage of a small number of cylinders in laboratories, outpatient departments and small processing plants; the large intelligent gas cylinder storage cabinets serve large-scale gas consumption scenarios such as chemical engineering, manufacturing and gas supply stations.Both take intelligent monitoring, explosion-proof design, anti-tipping fixation and digital management as core features, combining "human defense + technical defense" to reduce safety risks caused by human negligence.Against the backdrop of increasingly strict standards and regular safety inspections, gas cylinder storage can no longer remain at the extensive stage of merely having cabinets and assigned personnel. With a product philosophy of standardization, modularization and intelligence, DeSUN ECOTECH provides replicable, verifiable and traceable solutions for the design of both indoor and outdoor gas cylinder rooms.Whether for a few cylinders in a laboratory corner or large-batch centralized storage outdoors in factory areas, safe, compliant and efficient operation can be achieved within the regulatory framework. Enterprises can select corresponding intelligent storage cabinets according to their own gas consumption scale and scenarios, prevent risks in advance and consolidate the bottom line of gas cylinder safety management.

Recently, 30 sets of standard solid containers and standard liquid containers (customized non-standard versions) tailored by DeSUN ECOTECH for clients in Kazakhstan have completed production. The products have been packed strictly in accordance with export requirements and are ready to be shipped from China to Central Asia.These 30 units of equipment will be packed in export wooden cases suitable for long-distance road transport both within China and across borders. This delivery is far more than a regular order; it is a concentrated demonstration of DeSUN ECOTECH’s comprehensive capabilities in the field of safe turnover equipment for hazardous waste and hazardous chemicals. Every link, from product design and customized modification to export packaging and cross-border delivery, tests the professional competence of the enterprise.As an enterprise specializing in safe turnover equipment for hazardous waste and hazardous chemicals, DeSUN ECOTECH has always adhered to the core philosophy of "standardized design, scenario-based customization, and full-process safety". The exported standard solid containers and standard liquid containers retain standardized modules such as EU-standard pallet bases, stackability and forklift compatibility, but are customized in specific dimensions, interfaces, sealing structures and lifting positions according to the client’s actual operational needs.Starting from early demand research and material property analysis, the technical team carried out adaptive design for the containers in combination with local loading and unloading conditions and transportation practices in Kazakhstan. This design not only ensures safe turnover of specific materials, but also enables seamless integration with the client’s existing logistics and storage systems. During production, DeSUN ECOTECH strictly controls key processes including blanking, welding, hot-dip galvanizing, lining installation and leakage testing, to ensure that every container meets export standards in terms of strength, corrosion resistance, sealing performance and dimensional accuracy.1. Standard Liquid Containers: Leak-Proof, Corrosion-Resistant and StackableStandard liquid containers are one of the key products in this delivery. Positioned with core advantages of "standardized design, corrosion resistance, full sealing and intelligent IoT connectivity", they are specially built for temporary turnover and transit of liquid hazardous waste and hazardous chemicals.Made of carbon steel or stainless steel with hot-dip galvanized surface treatment and PP lining film, the containers are compatible with various liquid hazardous waste and chemicals such as acids, alkalis and organic solvents. The integrated sealing design, paired with large-diameter top lids, leak-proof sealing gaskets and anti-theft lock catches, effectively prevents liquid leakage and volatilization pollution, and reduces environmental risks during transportation and storage.Lifting lugs are installed at the bottom, and fixing slots are designed to prevent the containers from tipping over during transit. The EU-standard pallet base design supports stacked storage, improving space utilization by 50% and facilitating forklift and pallet transfer. A labeling area is reserved on the container surface for on-site personnel to mark material type, batch, weight and other information, enhancing the standardization and traceability of hazardous waste management.Standard liquid containers provide stable and reliable safety guarantees in scenarios such as liquid material turnover zones in chemical plants, liquid hazardous waste transit in hazardous waste treatment centers, liquid reagent turnover in laboratories, and liquid material transportation in the logistics industry.2. Standard Solid Containers: High-Strength, Fully Sealed and LabelableStandard solid containers focus on core functions of "sturdiness and durability, fully sealed dust protection, stackability and classified labeling". Made of thickened cold-rolled steel plates or stainless steel and treated with hot-dip galvanizing on the surface, they feature excellent impact resistance and wear resistance, and can meet the handling and stacking needs of various solid materials such as iron filings, batteries, sludge and animal carcasses.With an additional plastic lining, they can also adapt to highly corrosive substances, further expanding the application scope. The sealed cover plate design prevents dust escape and external contamination. Lifting lugs are arranged on the top of the box body to support stacking and reduce space occupation. Label holders are equipped on the container surface to support full-process identification of material type, batch and classification, helping enterprises achieve refined management in solid waste classification, storage and transit links.Whether in solid hazardous waste turnover zones in industrial parks, general industrial solid waste transit in manufacturing factories, solid sample turnover in laboratories, or centralized collection of solid materials in the recycling industry, standard solid containers can significantly improve turnover efficiency and space utilization.3. Export Packaging: Multi-Layer Protection for Cross-Border DeliveryIn cross-border delivery, packaging quality directly determines whether products can arrive at the client’s site safely. All products in this batch are packed in export wooden cases, principally fumigation-free plywood wooden cases that comply with international phytosanitary requirements for wooden packaging, avoiding delays in customs clearance caused by fumigation issues.Meanwhile, according to the structural characteristics of the products, DeSUN ECOTECH has equipped base supports, corner protectors, moisture-proof films, cushioning materials and internal strapping and fixing devices. The base supports and corner protectors enhance the overall strength of the cases and prevent local deformation during stacking and lifting. The moisture-proof film reduces the impact of humidity changes on metal containers during long-distance transportation. The cushioning materials and internal strapping and fixing devices effectively suppress displacement and collision caused by transportation bumps.This multi-layer protection system of "support – moisture proof – cushioning – fixation" not only protects the products, but also reflects DeSUN ECOTECH’s attention to detail in export delivery.4. Intelligent IoT Connectivity and Standardized Design: Boosting International Turnover EfficiencyIn addition, both standard solid containers and standard liquid containers can be optionally equipped with intelligent IoT functions such as positioning modules, smart locks and data transmission, realizing digital tracking and remote control throughout the turnover process.For cross-border projects like the one in Kazakhstan, clients can monitor the real-time location, opening/closing status and transit nodes of containers via the platform. This reduces management blind spots in the turnover of hazardous waste and chemicals, and improves safety and compliance levels. The standardized EU-standard pallet base design gives the products higher compatibility in the logistics systems of Central Asia and broader markets, reducing transit losses and efficiency losses caused by specification differences.5.

In the chemical, pharmaceutical, scientific research and industrial manufacturing sectors, the safe storage of flammable liquids has always been a top priority in enterprise safety management. An accidental fire can not only cause huge property losses, but also endanger personal safety and damage the ecological environment. How to ensure that safety storage cabinets for flammable liquids can hold their ground under extreme fire conditions and buy precious time for personnel evacuation and fire fighting is not only a mandatory regulatory requirement, but also a core concern of every responsible enterprise. Recently, the industrial-series flammable liquid safety storage cabinet (Model: DeSUN-FRC-TYP90) independently developed by Shanghai DeSUN ECOTECH CO., Ltd. (hereinafter referred to as "DeSUN ECOTECH") has successfully passed the strict fire resistance test conducted by SGS, the world’s authoritative testing and certification body. The test was carried out in accordance with the latest EU standard EN 14470-1:2023, and the product was finally awarded the highest fire resistance rating under this standard: Type 90 (90-minute type). This milestone achievement marks that DeSUN ECOTECH’s technical strength in the field of hazardous chemical safety storage has reached the international leading level, and sets a new benchmark for the quality of domestic flammable liquid safety storage cabinets. Authoritative Verification: Rigorous SGS Test Demonstrates Solid Technical Strength with Hard Data SGS is the world’s leading inspection, verification, testing and certification body, whose test reports are recognized by numerous authoritative institutions worldwide. This test was strictly implemented in accordance with the 2023 revised EU standard EN 14470-1 and conducted on June 16, 2026. During the test, the safety cabinet was placed in a test furnace simulating a real fire and heated continuously for 90 minutes following the standard time-temperature curve specified in EN 1363-1:2020. The average temperature inside the furnace was precisely controlled to strictly fit the standard curve, ensuring the authenticity and authority of the simulated environment. Under such harsh conditions, the performance of DeSUN ECOTECH’s flammable liquid safety storage cabinet was impressive. The standard requires that the temperature rise at any measuring point inside the cabinet shall not exceed 180 K (Kelvin). After 90 minutes of exposure to intense fire, the maximum temperature rise inside the cabinet was only 146.5 K. Calculated based on the ambient temperature of 26℃ at the start of the test, the maximum internal temperature of the cabinet was approximately 172.5℃, far below the upper limit of about 206℃ allowed by the standard, with sufficient temperature rise margin and excellent thermal insulation performance. Post-test inspection showed that although the cabinet body turned grayish white and the cabinet door was slightly deformed, there was no obvious abnormality inside except for minor discoloration. The cabinet door did not burst open and retained its locking function, with the overall structural integrity well maintained. This means that even in an extreme fire environment with an external temperature exceeding 900℃, the storage cabinet can still keep the internal temperature within a safe range and provide up to 90 minutes of effective protection for flammable liquids.

With the large-scale deployment of service robots in offline stores such as retail outlets, supermarkets and catering establishments, the daily indoor charging of robot lithium batteries has emerged as a highly overlooked safety risk in store operations. Featuring open spaces, dense pedestrian flow, abundant surrounding combustibles and a general lack of professional lithium battery safety operation and maintenance capabilities, traditional open charging modes are fraught with hidden dangers.To address this issue, a Shanghai-based intelligent technology company has introduced customized lithium battery charging protection cabinets from DeSUN ECOTECH. Tailored to the actual scenarios of stores, the solution targeted resolves multiple charging pain points. The following elaborates on the pain points and corresponding solutions respectively.Five Core Pain Points and Hidden Risks of Indoor Battery Charging in Stores1. Limited space with heavily overlapping charging and operational areasConstrained by floor space, charging areas in stores usually intermingle with product displays and pedestrian routes, lacking independent safety isolation spaces. Once thermal runaway occurs in lithium batteries due to overcharging or internal short circuits, open flames and high temperatures will quickly spread to surrounding goods and personnel, easily causing property losses and safety accidents.2. Concentrated battery placement triggers chain reactions from thermal runawayUnder the traditional charging mode, multiple batteries are charged in a concentrated area. When thermal runaway occurs in a single battery, it will rapidly ignite adjacent batteries and trigger a catastrophic chain reaction, exponentially increasing the difficulty of fire extinguishment.3. Insufficient professional competence of frontline staff with limited emergency response experienceFrontline store staff generally lack professional knowledge of lithium battery safety, with inadequate ability to identify early warning signs such as battery swelling and abnormal heating, as well as scarce emergency response experience, which often leads to missed optimal intervention opportunities.4. Unattended overnight charging allows minor hazards to escalate into major accidentsMany stores choose to charge batteries after closing at night, with the entire process left completely unattended. Fires cannot be detected and extinguished at the earliest moment, and even minor hidden dangers may escalate into severe accidents without intervention.5. Tightening safety supervision exposes non-compliant charging to regulatory risksCurrently, safety supervision over lithium battery charging in business premises is becoming increasingly strict across regions. Non-compliant charging practices face practical pressures such as rectification requirements and penalties, adding to the operational burden of stores.DeSUN ECOTECH Charging Protection Cabinets: Five-Layer Protection with Targeted SolutionsFirst Layer: Double-layer fireproof sealed cabinet structure blocks external fire spreadTargeting the pain points of compact charging spaces and abundant surrounding combustibles in stores, the charging cabinet adopts a fully sealed structure of double-layer steel plates with fire insulation layers, paired with flame-retardant sealing strips to achieve complete airtightness of the compartment. The entire cabinet has passed national explosion-proof certification and authoritative fire performance testing. Even in the event of extreme thermal runaway of batteries inside the compartment, flames and high temperatures can be firmly contained within the cabinet, providing reliable protection for surrounding personnel and goods.Meanwhile, the cabinet is optimized specifically for indoor scenarios. It does not require extra large floor space and can be flexibly placed in store storage rooms, back offices and other areas. Without disrupting normal operational flow, it creates an independent safety protection space for battery charging.Second Layer: Independent physically isolated compartments prevent thermal runaway chain reactionsTo address the chain reaction risk of concentrated charging of multiple batteries, the charging cabinet features a design with multiple independent compartments, with strict physical isolation between each compartment. Each battery is charged separately in an independent compartment, structurally blocking the spread path of thermal runaway from a single battery to others, and greatly reducing the probability of chain combustion and explosion.Each independent compartment is equipped with dedicated temperature and smoke detection devices as well as fire suppression components, which can accurately identify abnormal conditions in a single compartment and activate targeted protection. Protection triggered in one compartment will not affect the normal charging of others, ensuring safety while minimizing the impact of abnormal conditions on overall charging scheduling.Third Layer: Full-chain electrical protection and simplified operation for most O&M scenariosTo eliminate electrical safety risks during charging, the cabinets are equipped with a full set of professional power distribution systems, integrating multiple electrical protection mechanisms such as leakage protection, overload protection and short circuit protection. It avoids safety problems caused by circuit faults from the charging source, and fully complies with power consumption specifications for indoor commercial scenarios.Easy-to-understand emergency stop buttons and status indicators are installed on the front of the cabinet, with an external high-decibel audible and visual alarm. When abnormalities occur, it automatically triggers audible and visual warnings. With simple and intuitive operation logic, ordinary store staff can quickly complete emergency power-off operations. An emergency fire blanket is also provided inside the cabinet to handle initial emergencies, significantly reducing reliance on professional operation and maintenance capabilities.Fourth Layer: Intelligent IoT remote management fills unattended supervision gapsTo address the supervision gap of unattended overnight charging in stores, the equipment is equipped with a self-developed IoT management and control system from DeSUN ECOTECH, with a touch display interface.
